I have an 06, My first set lasted less than 12,000 miles. wear on inside edge of both frt tires. Dealer blaimed front end out of alignment,so we had the dealership align the front end. We had the dealer put down the before setting and after settings. They were almost the same, Called Lexus and pitched a B%^#@ and was reimbursed the cost of the alignment.
It comes down to the factory set are very high performance and very soft, this will =fast wear. You have to make a choice, performance or longevity. I have a set of michelins on now. Almost 50,000 miles no issues with no uneven wear patterns
